Structural deformation modifies the bandgap, exciton fine structure and phonon energy of semiconductors, providing an additional knob to control their optical properties. The impact can be exploited in colloidal semiconductor quantum dots (QDs), wherein structural stresses can be imposed in three dimensions while defect formation is suppressed by controlling surface growth kinetics. Yet, the control over the structural deformation of QDs free from optically active defects has not been reached.

- - The shape and structure of heterostructured semiconductor nanocrystals (h-NCs) are crucial for determining how effectively they can transport charge and how they behave in photonic applications.
- - There has been a challenge in managing the structure of III-V/II-VI h-NCs made of non-toxic materials, but this research focuses on controlling the growth of ZnSe layers on Indium Phosphide (InP) nanocrystals as a case study.
- - By manipulating the growth rates of ZnSe on different surfaces of InP, the study achieves a desirable morphology that enhances the light-emitting properties of InP/ZnSe h-NCs, allowing them to be more adaptable for various applications in optics
